arduino Multiple Buttons on one pin Electrical Engineering Stack
Here is a circuit that allows you to use five buttons; up, down, left, right and select, on one analogue pin with the Arduino. It is a adaptation of one used on this LCD shield manufactured by DF Robot. I have used a 10K pull-up resistor and added a 100nF capacitor to help with debounce.

Multiple Buttons: debouncing + state + counting + detecting the pressing and releasing events
Starting with arduino Multiple buttons on 1 pin hubpages
1 The trick for using analog pins for buttons is to create a voltage divider: simulate this circuit - Schematic created using CircuitLab The voltage on Ain will then depend on which buttons are pressed and the values of the resistors; the number of buttons you can chain together like this is dependent only on the resolution of the ADC.

How to interface multiple push buttons to one Arduino Interrupt pin
The Arduino uno board has 12 availabe digital I/O pins and 6 analog input pins, sometimes, on complex or 'big' projects, we run out of digital pins. In this tutorial you will learn how to use multiple buttons on one analog pin.,For example, if you have 4 buttons, you will need 4 digital pins to read them. But, if you connect them all together, with different resistors, you can read them from.
Arduino Multiple Buttons on One Pin FlyAndWire
In this tutorial, we will learn to interface multiple push-buttons on 1 pin in Arduino using Analog-to-Digital Converter (ADC). Why would we need to connect multiple push-buttons to one pin? Because microcontrollers come with a limited number of I/O pins. By interfacing many switches to one pin, we can save pins for other uses.
Analog Keypad or Multiple Buttons on A single Arduino Pins [code
In this Tutorial video, I'm going to be showing you how to connect up to 50 pushbuttons to a single Arduino analogue input. This enables you to free up a lot.
Analog Button Array
Connect Multiple Push Buttons To Multiple Digital IO Pins The problem comes in when you need to use multiple buttons. A 10 digit keypad for example uses 12 inputs, 10 digits from 0 to 9 and then a further two for the * and # keys. Let have a look at how we'd connect 5 push buttons using the standard digital IO method.

Подключение нескольких кнопок к одному аналоговому входу Arduino блог
By implementing multiple buttons on a single analog pin, you can conserve precious digital pins on your Arduino Uno board. This technique is particularly useful when working with projects that require a large number of buttons or have limited pin availability. You can apply this method in various applications, including:

Basic Arduino Circuit Diagram
AIN1. When the voltage on the positive pin AIN0 is higher than the voltage on the negative pin AIN1, the Analog Comparator output, ACO, is set. The comparator's output can be set to trigger the Timer/Counter1 Input Capture function. In addition, the comparator can trigger a separate interrupt, exclusive to the Analog Comparator.
Arduino Multiple Buttons To 1 Pin Using ADC
If you are using the internal pullup resistors, connect one side of each button to the pin and connect the other side of each button to ground. Whenever any of the three buttons is pressed, the pin will be low. If none of the buttons are pressed, the pin will be high. If you connect three buttons together in parallel, it will work as you want.
Multiple Push Buttons on One Arduino Input The DIY Life
Here is an easy way to use 1 analog pin to handle many input buttons. The way it works is very straightforward: use a resistor network as voltage dividers, and then let each button feed a different voltage to the analog pin. Thus by detecting the voltage we can tell which button has been pressed. Download the corresponding Arduino sketch code.
